my first track bike, a Bob Jackson had nice paint and chrome...

I ended up installing a Phil bottom bracket assembly. guy assembling it should have known better and or said something after installing the traditional BB.
the shell was one that had the Jackson lads in the shop really honking down on the bench vise, distorted the shell.
after I was was working at the importing shop, to get parallel faces would have reduced the shell to a 66.5mm wide.

There was a reason why most of those frames were upsold to Phil BB's.

In 1974 Bob visited the shop and I discussed the issue, he did not avoid it but said when I was to order a new pair he would upgrade the BB shells to the new Roto investment cast units gratis.
I ordered a Masi from Carlsbad instead.
matching road and track bikes was a SoCal top tier junior racer goal.
I had the satisfaction of buying them myself, my competitors had interested, wealthy enough parents. Hetchins, Pogliaghi, Norman Fey, Motobecane among some brands.
